The second edition of the International Competition on Computational Models of Argument will be conducted in the first half of 2017. The results will be presented at the Internation Workshop on Theory and Applications of Formal Argument (TAFA'17) which will be co-located with the 26th International Joint Conference on Artificial Intelligence.

The first edition of ICCMA took place in 2015 and saw the participation of 18 solvers. A summary report on the competition has been published in the AI Magazine.

ICCMA'17 will focus on reasoning tasks in abstract argumentation frameworks, cf. [Dung 1995]. Submitted solvers will be tested on several artificially generated argumentation frameworks and some frameworks formalizing real-world problems.

The competition will consist of 7 main tracks, one for each semantics:

  1. Complete Semantics
  2. Preferred Semantics
  3. Stable Semantics
  4. Semi-stable Semantics [Caminada et. al. 2012]
  5. Stage Semantics [Verheij 1996]
  6. Grounded Semantics
  7. Ideal Semantics [Dung et. al. 2007]

Each track will include the following reasoning problems (only a. and c. for grounded and ideal):

  1. Given an abstract argumentation framework, determine some extension
  2. Given an abstract argumentation framework, determine all extensions
  3. Given an abstract argumentation framework and some argument, decide whether the given argument is credulously inferred
  4. Given an abstract argumentation framework and some argument, decide whether the given argument is skeptically inferred

Finally, the special track “Dung's Triathlon” will require solvers to enumerate all extensions of all standard Dung-semantics (complete, preferred, stable, grounded) at once.

TAFA 2017 features a system track particularly suited for, but not limited to, ICCMA participants to submit extended 5 page system descriptions.
